Revolutionizing Blockchain: The Introduction of Ouroboros Leios on Cardano
In the recent Essential Cardano360 broadcast, Input Output Global (IOG) unveiled exciting advancements in blockchain technology with the introduction of Ouroboros Leios. This innovative consensus mechanism promises to elevate Cardano into one of the most rapid blockchain platforms, potentially setting new standards in the industry. Brian Bush, a Senior Prototyping Engineer at IOG, provided a glimpse into the technical intricacies that mark this pivotal stage in Cardano’s growth.
Cardano’s Next Big Leap Forward
Brian Bush elucidated the transformative potential of Ouroboros Leios, which introduces two new block types to operate alongside the existing Ouroboros Praos blocks. These new blocks are designed to significantly boost transaction throughput. Bush stated, “We are introducing two additional types of blocks beyond the traditional Praos blocks. One of these is the input block, which encompasses transactions and can occur at an exceptionally high frequency. This means input blocks, laden with transactions, could happen every few seconds or even faster.”

These high-frequency input blocks are subsequently referenced by endorser blocks, which undergo collective verification by the network. Bush described this process as a “hierarchy” that facilitates the secure aggregation of transactions. He explained, “The endorser block references these grouped transactions. Nodes then vote on these blocks to ensure all transactions are secure and verified, and these references are incorporated into the Praos block. This creates a hierarchical system that directs more transactions into the blockchain in a provably secure manner.”
Furthermore, Bush emphasized the potential of Ouroboros Leios to place Cardano at the forefront of blockchain scalability. While the outcomes are subject to ongoing evaluations, he expressed optimism: “The results depend heavily on our current assessments. However, if successful, we could achieve the fastest Nakamoto-style consensus mechanism and become one of the fastest blockchains globally.”
This development is poised to liberate developers working on Cardano from concerns about transaction throughput constraints. Bush added, “For developers creating applications on Cardano, transaction throughput will no longer be a limiting factor.”
Insights from Charles Hoskinson on Ouroboros Leios
Earlier this month, Cardano’s visionary founder, Charles Hoskinson, addressed the community during an Ask Me Anything (AMA) session, outlining the strategic roadmap for Cardano’s upcoming protocol advancements. He shared, “Our published roadmap includes everything the community has been asking for, including Midgard and Leios, with the goal of making Leios a first-class citizen. I’ve instructed the development teams to explore ways to implement Leios after prototyping, operating around the clock.”
Hoskinson highlighted an unprecedented 24/7 development model, underscoring the urgency and significance of realizing Ouroboros Leios. He stated, “We will deploy stacked development teams working day shifts, night shifts, and weekends. This approach has never been attempted in a cryptocurrency project’s history, illustrating the critical importance of this protocol, as it will position us among the world’s fastest cryptocurrencies.”
He also addressed the integration of Midgard and rollup solutions as part of a comprehensive strategy to forge a robust Layer 2 ecosystem. “With Midgard and Rollups, we aim to establish the fastest and most advanced Layer 2 ecosystem, surpassing Ethereum’s capabilities due to extended UTXOs and unique security properties.”
At the time of writing, ADA is trading at $0.7756, with market analysts closely monitoring its trajectory as it approaches the 0.236 Fibonacci level.
